8.1 Fault Management
A pending fault activates the yellow LED (Fault).
The integrated fault management records the first 50 occurred faults with time
stamps in the menu “System Errors”. The timestamp shows the days, hours and
minutes that have elapsed since the fault has occurred.
Additionally, a record of the faults occurs in the “Error memory”, which can only be read and deleted by the
service technician (code level 1 (3)).
8.1.1 Error Memory
The menu “Error Memory” in the main menu “System Errors” can only be opened via the code level priority 1.
In the error memory, the first 50 faults that have occurred and have already been acknowledged in the menu
“Error Status” are listed for the service technician in a power failure safe way.
Attention:
This memory should always be read during maintenance, relevant faults should be tracked and entered
in the service logbook, and finally the memory should be emptied.
8.1.2 System Messages and System Errors
The warning device includes a diagnostic module for the continuous monitoring of the relevant functions and
parameters as well as a processor-independent watchdog. These features set the device into the safe mode
"Fault" in case of an internal or external error. The following table shows all possible errors, possible causes,
the related troubleshooting and the resulting device status.
Once the cause has been eliminated, the warning device restarts with the diagnostic mode on its own. It isn’t
necessary to acknowledge the error message. In the event of an error, the error is output as plain text in the
version with display instead of the measured value and in the Error status menu. In case of two or more errors,
the value is output with a cumulative, bit-coded error code.
